The app is great and worth the money...if you have a relatively newer phone. With my iPhone 4 in the settings everything below text to speech option is unreachable due to smaller screen size. The same thing is with workouts where only 5 of them is possible to have, as well as with only 3 exercises per workout - only because + button is unreachable. When this is fixed it will get 5 stars as now it looks like more of a demo app.
